Using 32 bit windows PDB

[rado]

I cannot use PDB for x86 debug builds in last versions downloaded from spotifycdn (I've tried cef_binary_104.4.25+gd80d467+chromium-104.0.5112.102_windows32 and cef_binary_105.3.38+g2a6a54b+chromium-105.0.5195.102_windows32).
I've tried to load it in:
Visual Studio 2022 (symbol load information says PDB format is not supported)
WinDBG 10.0.22621 x86 (libcef.dll.pdb - dia error 0x8007000e)
WinDBG 10.0.22621 x64 (libcef.dll.pdb - file system or network error reading pdb)

I guess the reason could be that PDB file is almost 4GB big. Here is some information: https://developercommunity.visualstudio ... n-a/904784
Although MS claims it is fixed, it does not work for me. There is the " /pdbpagesize:8192 " argument mentioned, maybe it is not used in cef build?

We had to increase the page size recently because builds were failing. Is your VS2022 install completely up-to-date?

I have latest stable version Version 17.3.4 (updated today).

Maybe the fixed version isn't actually released yet? The "we fixed it" message was only posted on Sept 1, 2022.

At this moment I'm afraid to upgrade to preview version as I'll need to do some builds, so I'll try the other day, I don't need to debug it today.
I wonder if it is possible to debug chromium by placing breakpoints without building it? I mean using spotifycdn builds + cef PDB + chromium sources? But I haven't found way how to get chromium sources for chosen CEF version.

Can you use a 64-bit build instead?

[rado]

I'll try next time. Maybe I'll switch to 64bit, I hope there are not many users of 32 bit windows nowadays

I suspect this loading issue might only be with VS2022.

Symbols are loading successfully for me using VS2019 16.11.19 and CEF M107. I've tested both 32-bit and 64-bit builds with both Debug and Release symbols. Note with Release builds you need to enable symbol generation under "Configuration Properties > Linker > Debugging > Generate Debug Info" or breakpoints won't work in the sample app code.

Hi! Sorry to resucitate this otherwise dead and buried post, but I am facing the same problem. I'm trying to debug libcef.dll in VS 2019 and, when I try to load the pdb file, it says no symbols were found.

Are you using a fully up-to-date VS version? Did you download the correct/matching PDB file version?
